Abstract
In a method for implementing data conversion in a cloud data center, a backup server receives a read request from a block storage server. The read request includes a uniform resource locator (URL) address of a to-be-read virtual image object on the backup server and an address range of target data in the to-be-read virtual image object. The backup server obtains an address mapping bitmap and a storage path of backup data in a backup replica corresponding to the to-be-read virtual image object according to the URL address. Thereafter, the backup server obtains the target data from a storage device according to the address range of the target data and the address mapping bitmap and the storage path. Further, the backup server sends the target data to the block storage server. Hence, the conversion time of a backup data object may be shortened.
